Automotive drivetrain expert witness candidates typically have expertise and backgrounds in electrical engineering, mechanical engineering, product design, and/or automotive engineering. Representing the plaintiff or defendant, Cahn Litigation is often called upon to locate an expert witness to support automotive industry matters including cases involving drivetrain technology.

A drivetrain is a group of components that work with the engine to rotate the wheels; these components commonly consist of the transmission, differential, driveshaft, axles, CV joints, and the wheels. Cahn Litigation Services has dealt with drivetrain matters involving heavy equipment, commercial vehicles, diesel mechanics, vehicle design, as well as four wheel drive ATV off road vehicles, to name a few.

Often, matters requiring drivetrain expert witness services involve intellectual property, such as patent infringement litigation, inter partes review in the PTAB, or trade secret disputes. A forensic expert can reverse engineer components to prove (or disprove) intellectual property infringement or theft. A specialist in drivetrain technology might also provide testimony in a torts matter like personal injury or a product liability case involving vehicle failure analysis, or to assist in collision reconstruction.

Litigation support by an automotive expert with drivetrain expertise could include reverse engineering, accident reconstruction, expert reports, expert opinion, and expert witness testimony at a trial. In a high-profile case, or litigation involving a significant financial stake, a law firm may request a professional with prior expert witness experience. An expert witness needs to not only have expertise, an automotive expert witness must possess the ability to explain evidence to a jury. In addition, clients may seek an industry expert for pre-litigation consulting work.
